GAS-STOVE-VALVE-LOGNG DEVICE.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed November 21, 1907. Serial No. 403,129.

To all whom it may concern:

Be it known that I, WILLIAM SOHWERING, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in Gas-Stove-Valve-Locking Devices, of which the following is a specification.

This invention relates to a gas stove valve locking device, the objectbeing to provide a locking device which can be readily attached to anordinary stove now in use whereby all liability of the valve beingturned accidentally is prevented.

Anot ier object of my invention is to provide a locking device which isadapted to be placed adjacent to each valve on the gas stove so thateach valve can be opened and closed independently of each other.

A further object of my invention is to rovide very novel means forlocking the loc ing member, which is adapted toen age the handle of thevalve, whereby allcI locking member being moved is prevented. a

A further object is to provide a device which is exceedingly cheap inconstruction and one which can be attached to a gas stove in a very fewminutes.

These objects are obtained b the novel arrangement and construction 0parts hereinafter fully described and shown in the accompanying drawingsin which Figure 1, is a front view of a portion of a gas stove, showingthe application of my improved locking device. Fig. 2, is a top planview of the same. Fig. 3, 1s a section taken on line 33 of Fig. 1. Fig.4, is an end view of one of the locking devices detached, and, Fig. 5,is a section taken on line 55 of Fig. 1.

Referring to the drawings A, indicates a portion of the to of anordinary gas stove which is provide with a flange A, through which thefeed pipes B, leading to the burner are adapted to extend, the ends ofthe feed pipes B, being connected with a supply pipe C, all of which arethe ordinary construction now in use.

Each of the feed pipes B, are provided with a valve casing in which ismounted a turning plug I), carrying a handle D, for opening and,

closing the valves.

Openings are formed in the depending flange A to one side of the feedpipes andin a plane above the same through which is adapted to extend athreaded bolt E, of the anger of the member E, forming the fixed memberof my improved locking device, the bolt being secured therein by nut Eit of course, being understood that the openings can be formed in theflanged. part of the top when the stove is being made if desired.-

The member E, is provided with an ear E over which is pivotally mountedthe space ears F, of the pivoted locking member F, the members beingsecured together by a rivet F.

The pivoted memberF, is provided with a depending arm G, at its lowerend which'is flanged outwardly, as shown at G, so it will not engage theplu of the valve when turned down alon side of the handle D, as shown,which will ock the plug in a closed position whereby it will beimpossible to,move the same without raising the member F. It will alsobe seen that when the pivoted member is thrown down after the valve hasbeen opened, the valve will be locked in that position.

Pivotally mounted on'the member F, is an auxiliary locking clip H, whichis bowed as shown at H, and is provided with a pin H whereby it can bereadily swung on its pivot and it will be seen that when swung into poawhich is adapts to engage one side 0 member E, to prevent 'the cli fromswinging too far around so that": will e held over the fixed and ivotedmember whereby the pivoted mem er will 'be prevented from being movedupwardly.

rom the foregoing description it will be.

seen that I have rovided a-locking device for each valve, eac one ofwhich can be 0 erated independently so that. any one of t e valves canbe locked, closed or opened by simply throwing the cli to one side andswin ing the arm upward y so as to allow the hancfie to be turned,whereby the valve can be locked in any position desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. The combination with a gas stove provided with valves, of fixedmembers, a member pivoted to said fixed members provided with arms forlocking said valves and means for locking said pivoted members.

2. The combination with a gas stove pro vided with valves, of a membersecured to said stove, a member pivoted to said member provided with adepending arm adapted to e normally held in en agement wlth the handleof one of said valves and means for lockin said pivoted member.

3. he combination with a gas stove provided with valves, of lockingmembers pivotally connected to said stove adapted to lock said valves,closed or opened, and means for locking said locking members, for thepurpose described.

4. The combination with a gas stove provided with a plurality of feedpipes having valves arranged therein, "of members detachably secured tothe top of the stove, members pivotally mounted on the first mentionedmembers, said' pivoted member being provided with de ending arms and clis pivotally mounte on the pivoted meml iers for locking said ivotedmember, for the purpose describe '5. The combination with a gas stoveprovided with feed pipes carrying valves, of members fixed to the top ofthe stove. adjacent each valve, said members being provided with ears,members provided with space ears pivotally mounted on the ears of t efixed members by rivets, said pivoted" members being provided withdepending arms and clips pivotally mounted on the pivoted members,provided with lugs ada ted to engage said fixed members where y i saidpivoted members will be locked when said clips are thrown into;alinement with said members.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM SCHWERING.
